Hysteroscope for preventing outflow of uterine distension fluidTechnical Field
The utility model relates to the technical field of medical appliances, in particular to a hysteroscope for preventing the outflow of uterine distending fluid.
Background
Hysteroscopy is the procedure of looking at the cervical canal and uterine cavity under hysteroscopic direct vision, observing changes in endometrium, uterine morphology and placeholder lesions. The hysteroscopy can directly and carefully observe the tissue structures on the surfaces of endometrium and focus, is more accurate in diagnosis than the traditional blind uterine curettage method and the like, and can accurately draw materials of suspected lesion parts. At present, the gynecological hysteroscope direct vision biopsy method has replaced blind diagnostic uterine curettage, can find endometrial cancer and precancerous lesions, can diagnose endometrial polyps and submucosal myomas, can position ectopic intrauterine devices, evaluate the shape and size of uterine cavities, see clearly the mediastinum uteri and Gong Qiangnian links, and can also perform tubal intubation. Besides the diagnostic function, hysteroscopes can also be used for some hysteroscopic electrotomy, including electrotomy of endometrium, excision of endometrial polyp, excision of submucosal myoma, and trim cut.
The hysteroscope enters the cervical canal through the cervical external orifice, and the bulge Gong Ye is injected into the uterus, so that the whole uterus gradually bulges, and the hysteroscope slowly enters the cervical canal along the cervical canal and finally reaches the uterine cavity. After the hysteroscope reaches the uterine fundus, the hysteroscope starts to slowly withdraw, the shape of the whole uterine cavity is watched, the uterine fundus, the uterine anterior wall, the uterine posterior wall, two side walls and uterine horns, namely openings of uterine tubes at two sides are watched in sequence, and then the hysteroscope slowly withdraws into a cervical canal to check the condition in the cervical canal. Indications for hysteroscopy include abnormal uterine bleeding, suspicious submucosal myomas, endometrial polyps, endometrial lesions, intrauterine devices, and the localization and attempted removal of other intrauterine foreign bodies. Hysteroscopy can be used to further confirm that there is an adhesion in the uterine cavity, as can be found by non-invasive examination, such as hysterography, B-ultrasound, nuclear magnetism, and CT. In addition, for the infertility patients, hysteroscopy can be used to assist diagnosis.
At present, a hysteroscope is clinically inspected to have certain limitation, if a cervical orifice of a patient is loose, a hysteroscope device cannot be in close contact with the cervical orifice, gong Qiangpeng uterine liquid can continuously flow out along the cervical orifice along with the increase of uterine cavity pressure, and poor uterine effect, unclear visual field and poor uterine effect are caused; when cervical insufficiency, cervical relaxation or uterine perforation occurs during operation, the uterine cavity can be expanded poorly, and the uterine cavity is displayed unclearly, which is easy to cause incomplete cutting or uterine injury. The treatment method usually uses cervical suture or cervical forceps to clamp the front and back lips of the cervix, but the cervix is easily damaged, or the clamping failure is caused by short cervical and vaginal part or cervical hypertrophy.
